SHADE-ROLLER.

j Pater Application filed February 4, le s. Serial No. 6,047.

Be'it known that 1,. DAVID A. Lawn,

citizen of the United States, residingat Austin, in the county of Travisand State ofTeXas, have invented certain new and useful Improvements inShade-Rollers, of which the following is a specifica-tion-J Thisinvention relates to an improvement in Window shades and moreparticularly: to 10 an improvement in shade. rollers and brackets. I

It is well known that'window shades are generally very insecurelyfastened to their rollers, and that often times by pulling a shade fulllengthit is ripped ortorn from the roller, thus necessitating eitherthe-purchase of a new shade and roller or the ex penditure of much timeand labor in repairroller. p

It is the principal object of this invention to obviate the abovementioned objections by providing means I whereby downward pull of theshade" will be stopped while yet a turn or two of the shade remains onthe roller, so as to prevent accidental ripping or tearing of the shadefrom its roller.

Another object of the invention is to pro-. vide an improved device ofthe class described; incorporating aspring'actua-ted detent or pawlnormally tending to move into a recess'provided in the-roller forlimiting or stopping the rotary movement of the latter, the pawl beingnormally maintained out of engagement with the recess by the action ofthe curtain in covering the recess as the curtain rolls upon its roller,"the curtain however being provided .with a cut-away portion adaptedwhen there are'only a few will be extremely simple durable efiicientinoperation and "inexpensii e to manufacture.

With these and other objects in view which will become apparent as thedescription proceeds, the invention resides in the construction,combination and arrangement of parts, hereinaftermore fully describedand claimed, and illustrated in the 'accompanying drawing, in whichlikecharacter's of reference indicate lil the several figures, of-w 'Figure1 represents a of one end of a shade; ciated' bracket and sha cording tomy inventior j a view in sectionltaken t tically on a plane indica by.the arrow.

Th supported on a 'windo ofbrackets, in the usual brackets being indicate and at its opposite encperiphery of the roller. roller is a metallic ca sleevel2 provided witlat 13 forming a lining shoulder of the recessi Pivotally connected 1 apawl 14: preferably in of material havingits into engagement withangular shaped piece 0 manner as'tojform a pending from the pawl Theshade 6 atone c at 4, the'width of the c ing substantially equal thewidth of the metal sl and may be actuated either by gravity or by aspring. It normally bears against the shade when the latter is wound, insuch position that when the recessed portion of the shade uncovers therecess in the roller, the pawl will drop into the recess and will beengaged by the shoulder 11 thereof in the manner indicated in Fig. 3.for stopping the rotary movement of the roller and hence. terminatlngthe downward movement of the shade while yet there is a turn or two ofthe shade left upon the roller so that the back 19 of the bracket.

lso

said shade cannotbe pulled out to its full extent and ripped or: tornapart or .away from the roller. p

In the arrangement shown in Figs.v 14t inclusive the means for mountingthe pawl consists of a bar 17 formed integrally with brackets 7 and bentat right angles thereto into engagementwith an ear 18 formed integrallywith and bent. at right angles to The bar 17 is disposed horizontallyandnpon it the rear end 20 of the pawl is loosely turned, in such mannerthat'the pawl may rock upon said bar. The pawl may be either spring orgravity actuated, and in the former case a length of spring materialindicated at 20 is turned upon. bar 17,- and at one end extends througha recess 21 in the upper edge of back 19 of the bracket into engagementwith the casing 8. The opposite end of the spring extends in theopposite direction and is projected upwardly through a slot indicated at22 in the pawl and bears.

against the upper face of the latter whereby said pawl may be maintainedin engagement with the roller.

In the form indicated in .Figs. 5 and 6 the bracket 7 is of the ordinarycommon type. Against the back 19 of this bracket is adapted to besecured a plate 23 having a right angular bent end 24; on which isintegrally. formed the bar 17 which bears at one end against an ear 18also formed on plate 23. On the bar 17 the pawl 14 is pivoted in theusual manner. In Figs; 5 and 6 also this pawl is adapted to be actuatedby gravity or by operation of the spring'indicated at 21 similar inarrangement and operation to spring 21.

In both structures shown in, the drawing the pawl is in such positionthat when therecess in the roller is uncovered by wit-h-.

drawing the shade from the roller the pawl whereov the curtain mar willdrop into the recess to be engaged against its shoulder for stopping thewith drawal of the shade.

Upon jerking the shade and releasing it'in the ordinary manner theroller will be actuated in a reversed direction so as to roll the shadeupon it, and as it moves in the reverse direction the pawl will rideover the floor of the re cess onto the periphery of the roller and overthe turns of the shade as the latter becomes wound on the roller. Thefree passage of the shade up and down is not interfered with in theleast by the action of th'e pawl in limiting the movement of the shade.

Therecess 9 is arranged at such point in the periphery of the roller,thatshoulder 11 will come in contact with the pawl just before theratchet mechanism, which is contained within the roller, and which is ofthe ordinary usual. construction, takes up another notch or clicks intolocking position for maintaining. the shade at adjusted height, so thatsuflicient play is allowed Q moved up and down to admit of the releaseofv the latch in the ratchet mechanism so as to allow starting of upwardmovement of the shade. 'Although I have described the preferredembodiment ofmy invention, I may desire to make such changes in theconstruction, combination and arrangement of parts thereof as do notdepart from the spirit of the invention and the scopeof the appendedclaims;
